digger760,
We are still debating the relative merits of a ranking system or a straight ladder.
Map size and start positions are not important, as long as the two playing agree what they want to do. Restarting is still under debate, but if two people agree the restart conditions before they start a game then all is fair again.
Declining games must be acceptable, but with some limits.
To bring up ERIKK's comment from post #16, a points system could include games with more than 2 human players, for example
100 standard,
+50 for a win,
+10 for winning against a higher player
-10 for losing against a lower player
+20 per player in a game with > 2 players (so +10 for 3 player, +20 for 4 players, etc).
more modifications needed here, including something akin to the chess system Mel suggested, but maybe a bit simpler...
